Symptom-based cross-domain dynamic anonymous Authentication group key management method and system

Abstract

The invention provides a symptom-based cross-domain dynamic anonymous authentication group key management method and system. By using the method provided by the invention, a patient can be diagnosed and treated by different medical institutions, the system allows a group of patients from different medial fields generating a group session key, thereby establishing a safety group communication. The system supports the anonymity and the traceability of the patient, the identity of the patient is hidden in the pseudonym, only an assigned mechanism can recover the real identity. A cross-domain group key protocol guarantees that the authenticated patients from different medical institutions and with the same symptom can generate the safety group key; the patients establish the safety group communication by using the key, thereby protecting the patient privacy information in an electronic medical social system. The system further supports the dynamic group management, when the group member is changed, the system can generate a new group session key.

Description

technical field [0001] The invention relates to a disease-based dynamic anonymous authentication group key management method and system in a cross-domain electronic medical social system. Background technique [0002] Electronic medical systems enable new pervasive computing for high-quality healthcare through electronic processing of medical data. The patient's condition can be monitored by collecting vital signs and other medical data through electronic medical devices or tiny sensors. In the medical system, medical personnel need to provide professional diagnosis of diseases and conditions for patients. On the other hand, these patients also intentionally communicate with other patients with the same condition. They hope to establish disease-based communication groups to exchange information about diseases, share treatment experience and expert advice. They can chat in the communication group, talk about their real-time disease status, and encourage each other to overc...

AI Technical Summary

Problems solved by technology

[0009] In view of the existing group key agreement schemes, which do not realize cross-domain secure group communication, cannot support group establishment based on disease matching, and have low efficiency, the present invention provides a disease-based cross-domain electronic medical social system. The dynamic anonymous authentication group key management scheme, which proposes a cross-domain group key agreement protocol, realizes patient anonymous identity verification based on disease matching, can support dynamic patient management and group management, and is more efficient than similar related program, and has high security
